Resolved Problems sharing/printing from a Win 7 printer, from an XP laptop

I have an HP LaserJet 1018, connected to a Win7 desktop. I can print from that desktop. I made sure that the laserjet was shared (from Win 7), made sure that my xp laptop was on the same workgroup, and followed instructions I found here, to create a new local port. XP Laptop was able to find the printer, and the drivers installed. But for some reason, I can't print to it. Can someone help me troubleshoot?

 

Never mind. I had also reserved an IP address on my wireless router, and doing this cut off my connection to the home network. Deleting that reserved IP got me back on again--printing is fine.
